[0010] The beneficial effects of the utility model include: high positioning accuracy, convenient clamping, the backward flipping of the pressure plate when taking and placing parts will not affect the robot to take and place parts, which significantly improves the clamping efficiency and reduces the labor intensity of workers. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0012] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0013] A kind of Figure 1 The laptop keyboard touch panel machine fixture shown includes a bottom plate 1, a top plate 2, and a positioning plate 3. The bottom plate 1 is used to be installed on a machine tool workbench. A plurality of pillars 4 are arranged between the bottom plate 1 and the top plate 2, and are used to lift the top plate 2 to a predetermined height for installation. The positioning plate 3 is arranged on the top surface of the top plate 2, and a front positioning block 5 and a side positioning column 6 are arranged on the positioning plate 3. The number of the front positioning blocks 5 is two, and they are arranged at intervals at the front end of the positioning plate 3. The number of the side positioning column 6 is one, and it is arranged on one side of the top surface of the positioning plate 3. It is used to position the laptop keyboard housing.

[0014] A pressing plate 7 is arranged above the positioning plate 3 to press the edge of the keyboard touch pad of the notepad. The pressing plate 7 has a hollow hole 71 corresponding to the touch pad, and the pressing plate 7 has an oblique chamfer 72 around the hollow hole 71. Therefore, the tool on the machine tool can extend into the hollow hole 71 to process the workpiece. A flip pressing mechanism for driving the pressing plate 7 is arranged on the top plate 2. The flip pressing mechanism includes two pressing cylinders 8 arranged on the top plate 2, and the piston rod end of the pressing cylinder 8 is hingedly connected to a pressing arm 9, and the two pressing arms 9 are arranged in parallel. A hinge support 10 is arranged on the cylinder body of each pressing cylinder 8, and a hinge plate 11 is hinged on the upper end of the hinge support 10. The rear part of the pressing arm 9 is hinged on the hinge plate 11, so that the pressing arm 9, the hinge plate 11, and the piston rod of the pressing cylinder 8 form a lever mechanism. The pressing plate 7 is connected to the free ends of the two pressing arms 9. During clamping, the two clamping cylinders 8 act synchronously, and drive the pressing plate 7 through the two pressing arms 9 to clamp the workpiece.

[0015] Furthermore, in order to prevent the pressing surface of the pressing plate 7 from being non-parallel to the top surface of the workpiece, the free end of the pressing arm 9 of this embodiment is connected with an adapter block 12, the middle part of the adapter block 12 is hinged to the pressing arm, and the adapter block 12 is fixedly connected to the top surface of the pressing plate 7. Thus, the pressing plate 7 can be closely attached to the top surface of the workpiece.
